“…The same isolation of western North Atlantic and western South Atlantic populations at mitochondrial markers also occurred in large coastal shark species such as Sphyrna lewini (Griffith & Smith, 1834); (Chapman, Pinhal, & Shivji, ), Carcharhinus leucas (Müller & Henle, 1839) (Karl et al, ), G. cirratum (Karl et al, ), Negaprion brevirostris (Poey, 1868) (Ashe et al, ), and the semi‐oceanic C. falciformis (Domingues et al, ), but not in epipelagic, oceanic shark species such as Pseudocarcharias kamoharai (Matsubara, 1937) and Carcharhinus longimanus (Poey, 1861) (Camargo et al, ; Ferrette et al, ). Individual based mtCR analyses support an isolation‐by‐distance pattern rather than the complete isolation of populations in night sharks, similar to findings for other shark species such as Carcharhinus melanopterus (Quoy & Gaimard, 1824) (Vignaud, Clua, Mourier, Maynard, & Planes, ), Sphyrna tiburo (Linnaeus, 1758) (Portnoy et al, ), and N. brevirostris (Ashe et al, ). A mito‐nuclear discordance was also found for night shark along the western Atlantic Ocean: individual‐based analysis (DAPC and structure ), based on nine microsatellite loci, did not reveal the structure observed in mitochondrial markers.…”
